Using cookbook recipes does more harm than good, all is needed is a good schedule reviewer capable of thinking by himself, capable of discerning between what is acceptable and what is not, capable of figuring out when exceptions to general rules make sense.

The differences among the US Agencies specifications and what is good practice and what is not is a proof that cookbook recipes do not make sense.
